the word "no"

Does anyones child actually listen and obey when you tell them NO? I try my best to limit its use or to find other ways of telling them to stop or leave something alone but sometimes its just impossible to avoid saying "no". However, when I say it LO has no reaction... doesn't stop what he is doing and could care less about what I'm saying, unless I physically move him or take what he has.

Sometimes L listens and sometimes he completely ignores me. I try to limit its use to only things that are dangerous to him. Otherwise I say "please don't do (whatever he's doing that I want him to stop)." He definitely knows what no means because he's constantly telling me "BO" when he doesn't want to do something or doesn't want a food or drink I'm offering him.

I feel like maybe I'm lucky with this, at least so far. He does usually stop what he's doing to at least acknowledge me and then most of the time, he will stop what he's doing and move on. I try to say "no no" in a somewhat friendly manner and I usually follow it with a reason, like "you're going to get a boo boo," or "that's not yours," etc and he will *usually* walk away.

However, sometimes if I say NO loudly or with a lot of force, he tends to want to resist me or he will throw whatever he's holding or bang his hand or head on the nearest table, floor, etc.

At my house, "No!" is like a dare or something. LO will stop sometimes if I'm conversational or suggestive, but any sort of authoritative tone makes him want to test me.

LO is the least tractible of all my kids. ODD would listen 99% of the time, ODS most of the time, and LO almost never. I don't think it's my parenting. I'm generally pretty strict. He's just super sassy.
